--- _id: '6972' abstract: - lang: eng text: "In recent years, a variety of different approaches\r\nhave been proposed to tackle the problem of scaling and placing\r\nnetwork services, consisting of interconnected virtual network\r\nfunctions (VNFs). This paper presents a placement abstraction\r\nlayer (PAL) that provides a clear and simple northbound interface\r\nfor using such algorithms while hiding their internal\r\nfunctionality and implementation. Through its southbound interface,\r\nPAL can connect to different back ends that evaluate\r\nthe calculated placements, e.g., using simulations, emulations, or\r\ntestbed approaches. As an example for such evaluation back ends,\r\nwe introduce a novel placement emulation framework (PEF)\r\nthat allows executing calculated placements using real, containerbased\r\nVNFs on real-world network topologies. In a case study,\r\nwe show how PAL and PEF facilitate reusing and evaluating\r\nplacement algorithms as well as validating their underlying\r\nmodels and performance claims." author: - first_name: Stefan Balthasar full_name: Schneider, Stefan Balthasar id: '35343' last_name: Schneider orcid: 0000-0001-8210-4011 - first_name: Manuel full_name: Peuster, Manuel id: '13271' last_name: Peuster - first_name: Holger full_name: Karl, Holger id: '126' last_name: Karl citation: ama: 'Schneider SB, Peuster M, Karl H.
